Targum Jonathan on Deuteronomy
When you make an end of tything all the tenths of your produce in the third year, which is the year of release, you shall give the first tenth to the Levites, the second tenth, which is the tythe of the poor, to the stranger, the orphan, and widow, that they may eat in your cities, and be satisfied.
Targum Jerusalem
When you finish tything all the tenths of your produce in the third year, which is the year of the tythe for the poor, you shall give the first tenth to the Levites, and the poor's tenth to the stranger, the orphan, and widow, that they may eat in your cities, and be satisfied.
